Managing the electromagnetic environment

As specialists in electromagnetic environment management, we make environmental health a priority by helping public and private sector players to better define their risk management policies. We support the responsible deployment of digital technology by designing innovative services and products with the aim of striking a balance between health and technological development.


Managing electromagnetic environments

As an accredited testing laboratory from the outset, we have built our identity in the rigorous world of regulatory testing. Coming from the world of academic research, over the years, we have instilled a dynamic of development that today enables us to place innovation at the heart of our service offering.


"As PhD graduates from the University of Toulouse at the height of the digital explosion, we created Exem to respond to the environmental health issues associated with the deployment of telecommunications infrastructures."

Companies & local authorities

Positioned in a new area that requires long-term thinking, we were determined to come up with innovative solutions to meet the social challenges . From 2015, we therefore set up a team of engineers dedicated to research and development.

Competition winner

of ENEDIS innovation

In 2015, we won the national innovation competition organised by ENEDIS for our work on underground power line detection.

The social debate taking shape in France in the 2010s led us to develop a solution designed for the general public. We have developed a sensor technology that now enables us to monitor public spaces with complete transparency via our EMF Observatory platform.



Recognised for our unique expertise, we have been selected by the French National Agency for Food, Environmental and Occupational Health and Safety for two studies aimed at examining the impact of new mobile uses on users’ exposure to electromagnetic fields, and the impact of industrial technologies such as welding on operators in the workplace.

In 2022, we have observed that local authorities, as part of their environmental health policy, need support on various aspects of exposure to electromagnetic fields. Thus we have developped a comprehensive and modular “EMF City Management” package to help public authorities manage exposure to electromagnetic fields.
